Application filed August 10, 1995, Serial No. 273.509.

To all whom it may concern:

Be it known that I, J OHN H. DAv1s,,a citizen of the United States,residing at Hamilton, Butler county, Ohio, -(post-ofiice address No. 229North Ninth street, Hamilton, Ohio,) have invented certain new anduseful Improvements in BalLCocks, of which the following is aspecification. 1

This invention, relating to that class 0 float-controlled supply valvesemployed in connection with tanks and generally known as ball cocksaimsto improve such cocks by better adapting them for use with water of akind liable to clog metal valve-parts working in contact, and to secureready rcmovability of the working parts. The cock is of that typeemploying a Compound lover system between the float and the valveproper. Y

The improvements will be readily under stood from the followingdescription taken in connection with the accompanying drawing in which VFigure 1 is a side elevation of my improved ball cock: Fig. 2' avertical section of the same: Fig. 3 a vertical section through thevalve chamber in a plane at right angles to the plane of the sectionshown in Fig. 2: and Fig. 4 a front elevation of one of the leverjoints.

In the drawing :-1, indicates the valve body, being a casting adapted toseat upon the floor of a tank, as usual: 2 the inlet nose thereto,adapted, as usual, to go through a hole in the floor of the tank andhave the supply pipe coupled to it below the tank: 3, the usual gasketto be clam ed between the valvebody and the floor of t e tank: 54, thevalvechamber, within the valve body 1: 5, the roof of the valve-chamber,the same being provided with' an upwardly projecting central boss havina circular aperture: 6, the valve proper, ein markedly smaller diameterthan said circular aperture, through which it extends without contactand having its lower end faced with rubber or analogous material, the uper end" of the valve proper being bifurcated 7, the inlet to thevalve-chamber, the same being formed by a central aperture extendingthrough a boss extendin upwardly from the floor of the valve-chain er,the annular top of this boss forming the valve-seat against 'which thelower end of'the valve proper seats: 8, an umbrella flange surroundingthe a cylindrical plug of valve proper above the roof boss through whichit projects, this flange coming as closely down to the top of the bossas is consistent with the proper seating of the valve in its originalcondition and in such condition as is liable to result from continueduse: 9, a bifurcated arm projecting rigidly up from the valve-body,parallel with the axis of the valve proper, and to a point some distanceabove the latter: '10,, the float lever, pivoted in the upper end of arm9, the long arm of this float lever projecting over but at all timesfree from the valve proper, and being adapted to carry the usual float,the short arm of this float lever projectingoutwardly from arm 9: 11,the pivot connecting the float lever with arm 9: 12, a bifurcated armprojecting rigidly upward from the valve body at a point diametricallyopposite arm 9: 13, a secondary lever having one end pivoted to the arm12, and an intermediate point pivoted to the bifurcated upper end of thevalve proper, the longer arm of this secondary lever projecting throughthe bifurcation of" arm 9, below the pivot 11in the latter, and to apoint outwardly beyond arm 9 so that .its outer end is below theoutwardly projecting short arm of the float lever: 14, the pivotconnecting secondary lever 13 with arm 12: 15, a link connecting the endof the long arm of the secondary lever, with the end of the short arm ofthe float lever and having such length that the secondary lever will besubstantially horizontal when the .valve is, closed: 16, the pivotuniting the upper end :of link 15 with the float lever: 17, the pivotuniting the lower end of the link with the secondary lever: 18, thepivot uniting the secondary lever with the valve pro er:-19, outletports in the base of the wal of the valve-chamber: 20, deflectingshields projecting outwardly from the valve-body over these ports: and21, a small pipe leading out-- wardly from the valve chamber.

In the drawing the valve is seen in closed position, in which action ofthe float t ough the medium of the compound leverage. The pressure isdirectly downward axially upon the valve proper, its body beingentirelyfiee from contact with and having considerable clearance on allsides from the wall' of the aperture in the roof of thevalve chamber,the secondary lever centering and reventing its displacement.

account and because of other features of con struction the valve 1snolseless in operation.

- The upper end of the valve pro er,when

thevalve is either 0 en or close is supported by the secon ary' lever-13 bridging the spacebetween'thefarms 9 and 12 and guided sidewise inthe'bifurcations of those arms. The valve proper .is'thus supported inall directions at. its upper end through the medium of the secondarylever.

In Fig. 4 the form of pivot-14 is'shown, .the

1privot being removable by being unscrewed om arm 12, the bend in theouter end ofthe pivot forming a convenient handle for turnmg it. Thepivots 11 and 14 are to be of the removable type indicated in. Fig. 4a'nd"it is pgreferable that pivot18 "also of this type.

y removing pivots 11 and 14, all of the movmg parts may be removedupwardly for inspection or repair, it not being necessary to remove thevalve body from the tank.

Pipe 21, serves, in the usual'manner, in connection with the reseal ifthe ball cock is usedin connection with a closetreq u-iringsuch feature.This pipe ma serve in the usual way to discharge resea 'ng water intothe flush ipe while the flush valve is open. When t e valve is open andthe supply water is discharging into the tank through ports 19 thelow-down location of those ports insures a complete'washing out of thevalve chamber, thus preventing the accumulation of foreign matters atthe face ofthevalve seat.-

- When the valve is open the valve plug lia'ngs as' a freely suspendedstructure, hangmg by pivot 18.

he engagement of the upper end of the plug with-lever 13 is such thatthe upper end of the valve can shift in neither direction, beingrevented from shift-mg endwise of the lever y the fitting of lproperrises and falls. The result is.

pivot. 18 in both the lever and the valve plug, while it is preventedfrom shifting in the otherdirection by the straddling of the lever bythe upper end of the valve plug. While the valve is thus open waterentering the valve chamber has two outlets, the main one being throughports 19 disposed below the level of the roo of the valve chamberw-hilethe secondary outlet is upward through the roof of thevalve chamberaround the valve plug. While the water is .flowin past the. open valvethere is thus a low,was in effect at the valve-seat and also a-high levewash ing efiect where the plug passes through the chamber roof. Thevalve is in practice found capable of perfect practical results, as toperformance and maintenance, under peculiarly bad water conditions whereother valves have given very serious trouble. The upward rush of waterthrough the roof of the valve chamber around the valve plug is preventedfrom spouting upward 'by reason of the presence'of the um rella flange.This flange is disposed some distance above the top of the roof holethrough which the valveplu works so as to give at all times a free outet sidewise to the water passing upwardly around the plug.

I-claim-as my invention In a ball cock, a valve'chamber having a supplyinlet and valve seat in its base and an having a dischargeoutletsidewise in its base, a valve-plug with its foot resting upon andopemng concentric therewith in its roof and closing said valve-seat andhaving its body I rojecting through the opening in the roof es ofcontact therewith, an' umbrella flange carried by the valve plug abovethe annular discharge opening within the roof opening around thevalve-plug so as to permit free sidewise discharge of the water passingup wardly through said annular opening, a lever mounted-on a fixed pivotand crossing the valve plug at its upper end and having sidewiseengagement therewith'so that the valve plug may not shift sidewiserelative to the lever, and a pivot en aging and fitting the lever andupper end 0 the valve plug in such manner as to prevent the shifting ofthe upper end of the valve plu endwise ofthe lever,"combined substantiay as set forth, whereby when the valve plug is raised it is freelysuspended by its upper end and whereby the flowing water is given a lowside outlet at the valve-seat and an upward and sidewise outlet abovethe valve chamber.
